Turbo seems boosting correctly.
The oil got sucked into the air filter housing has some yellow substance mixed in with the oil and the oil filler cap is cover with yellow paste substance also.


Thanks, Yahow
That yellow substance you're seeing is mixture of oil, water and air. Whenever you see that substance, it's a clear indicator that the engine is not getting up to temperature. Generally, you see this symptom in cars that are used only on short drives. Your oil problem may be due to high crankcase pressures from combustion gases escaping around piston rings or cracked piston(s). But....
It also may be due to that "yellow" substance in the engine breather system. This would cause higher than normal oil tank pressures pushing the oil up through the oil separator tank. I would suggest you get the engine up to full operating temperature for a while and then have the oil changed immediately.

Also, if you oil temp gauge never gets to the first small hash mark above the rest point, you are not at normal operating parameters. I would also suggest you change motor oil manufacturer. Go to Mobil 1 V-Twin 20-50 and you will never see sludge buildup. I'm sure there other good choices out there, but judging from your driving habits, this is a safe bet.
